This sure sounds like a failing hard drive to me. Over the years, I've had probably a dozen drives fail, almost always starting with I/O errors. A power cycle is frequently required. In fact, I'll be replacing a drive at home today! Having two drives doesn't improve things. The system is still going to try to access the failing drive and will still generate I/O errors. If rescue mode couldn't see the disk, you're probably out of luck. Sorry. Kirk Bocek Jean Lee wrote: > Hello, > > I have a problem with my server : > > Sometimes, this server is used to stop running.
